WEATHER-STRIP.

Specification of Letters Patent,

Patented Dec. 3, 1907.

Application led April 5| 1907. Serial NO- 366.616.

To all 'whom it may @encerrar Be it known that I, ALBERT BUJEwsKI, acitizen of the United States, residing at St. Louis, in the county ofSt. Louis Oity and State of Missouri, have invented a new and usefulWeather-Strip, of which the following is a specification.

This invention relates to a weather strip to be applied to windows anddoors for preventing the entrance of cold air and rain, the main objectof which invention is to produce a weatherI stripof suoli constructionthat when secured to the side or sides of a window sash or door, it willwhen the sash or door is opened, beautomatically drawn awayfroin thewindow or door frame and permit the sash to be raised and lowered or thedoor to be opened without frictional contact of'the weather strip withthe said frame, but on fully closing the window sash or door, suitabledevices will be broughtinto opera tion to force the weather striptightly against the window or door frame and effectually exclude allcold air and rain.

In the accompanying drawings :-Figure 1 is a view inelevation of a partof a window sash with my invention applied thereto, a portion beingshown in section. Fig. 2 is a cross sectional view on the line 2-2 ofFig. 1, enlarged. Fig. 3 is a vertical central sectional view of theinvention detached from a window sash. Fig. 4 is a view of the lowerpart of a door with the weather strip attached to the bottom thereof.Fig. 5 is a cross section on the line 5 5. Figs. 6 and 7 arerespectively views of the rear and front edges of the bottom of a doorshowing the securing plates for sustaining the weather stri l Siinilarnumerals ofA reference are employed to indicate corresponding artsthroughout the several iiguresof the rawings.

t window sash indicated by 1 is grooved in one or both sides, as at 2,from the bottom to or near the top thereof into which groove is inserteda channel bar 3 made of wood or metal, having a straight bottom 4 andparallel sides 5 perpendicular to the bottom 4. i

Within the channel bar 3 and bearing against its bottom'4 is alongitudinally movable operating bar 6, its sides bearing against thesides of the channel bar 3 and extending from the bottom of said channelbar to near its top.

Resting against the outer side of the operl ating bar 6 and extendingthe full length and width of the channel bar 3 is a fixed separatingstrip 12, on the inner face of which at each side is a flange 13, eachflange tting a suitably formed rabbet in an edge of the operating bar 6.The separating strip 12 is held in place in the channel bar by means ofnails or screws 14 or other suitable means, as shown, and has its outerface recessed at 15 as clearly indicated in the drawing, the purpose ofthese recesses will be disclosed later.

, Next the separating strip 12 and in contact therewith except when thewindow sash is completely closed is a rectangular rod 16, the fulllength of the channel bar 3, and provided on its outer face throughoutits entire length with a groove 17 in which is securely seated aresilient packing 18, preferably rectangular in cross section,projecting slightly beyond the outer face of its containing rod 16, Forconvenience in describing the invention, the rod 16 and its resilientpacking 18 will be called the weather strip. On the inner face of theweather strip project a plurality of cam studs 19, extending throughopenings 20 in the separating strip 12, and so disposed that the camsurface on the lower side of each stud is, in the relaxed position ofthe parts, just above a roller 10. From this it may be observed thatwhen the operating bar 6 is raised, the rollers 10 acting on the camstuds will force the weather strip outwardly.

Secured to the back of the rod 16 opposite each recess 15 in theseparating strip 12, is a fiat spring 21 fastened in place by a screw orrivet 22 passing through its center. The ends of each s ring, which arefree, extend under flat resilient metal plates 23 fastened at one end tothe separating strip 1'2 within each recess 15, forming thereby a springconnection between the separating strip 12 and the weather strip 16.

When this weather strip is used in connection with a window sash, one orboth sides of screws 14. An aperture 30 is made in the said sash aregrooved and a channel bar 3 seated in each groove and secured in anydesired manner. The coiled spring 8 bearing against a part 24 of thesash frame l tends to keep the operating bar 6 pressed downward and therollers l0 away from the cam studs y 19, thereby permitting the flatsprings to recoil {ijhand draw the weather strip into the channel bar 3.In this position the window may be raised and lowered with the greatestease as the resilient packing 18 is entirely out of contact with thewindow frame. When the window sash is closedjjLthepin 9 coming incontact with the bottom of' the window frame holds the operating barstationary, while the remaining parts of the device are descending. Asthe cam studs 1-9 come in contact with the rollers 10, the weather stripis forced laterally from the channel bar against the sides of the windowframe.

What has been said heretofore in connection with placing this device ona window sash is equally applicable when applied to doors and otherclosing devices. In attaching the weather strip to a door, andespecially on the bottom edge, a groove 25 is first made in the bottomedge of the door of a' size to receive the channel bar or casing 3 of`the weather strip. The weather strip eX- tends from the front edge tothe rear edge of the door, and is held in place within said groove by aplate 26 set into the front edge of the door and a plate 27 ilushwiththe rear edge. Screws 28 secure the plates 26, 27 to the door, butfor attaching the weather strip to the plates, screws 29 pass throughsaid plates into the ends of the separating strip l2 fastened to thechannel bar 3 by nails or rear plate 27 through which the pin 9projects, so that when the door is closed, the

, pin 9 striking the door frame slides the operating bar 6 endwise andforces the resilient packing 1S against the door sill.

I clairn:-

1. A weather strip comprising a casing, a longitudinally movable bar, atransversely movable bar, a ixed separating strip between the two bars,coperating means carried by the two bars for causing one of 'said barsto move the other in a direction transverse to the movement of the iirstmentioned bar, and interlocking spring plates fastened to the separatingstrip and to the transversely movable bar.

2. A weather strip comprising a casing, a longitudinally movable bar, atransversely movable bar, a fixed separating strip between the two barsprovided with through openings and exterior recesses, cooperating meanswithin said openings carried by the two bars for causing one of saidbars to move transversely when the other is moved longitudinally, aspring plate centrally iastened to the transversely movable bar oppositeeach recess in the separating strip, and other spring plates in the endsof said recesses arranged to overlap the ends of the spring plates onthe transversely movable In testimony that I claim the foregoing as myown, I havehereto affixed my signature in the presence of two witnesses.
